Is it possible to configure access to apache only through nginx?

Question

Nginx

Good day!
There is an apache server with a web resource. There is an nginx server that redirects requests to the apache server. There are proxy settings on nginx:

proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;

Is it possible to configure apache in such a way that it accepts requests only from nginx, and at the same time does not violate the proxy settings (real client ip addresses)?

Answer 1

Are they on the same car?
If yes, then just hang Apache on 127.0.0.1
. If not, then configure a firewall on the Apache machine to allow connections only from the nginx host.

Answer 2

mb close apache port
